| Summary: | Background: Intrauterine Device (IUD) is an effective and long term method of contraception that can be used without continued effort by the user to prevent pregnancy perfectly. Pain during IUD insertion is one of the obstacles to properly using the device. Thus, using different methods of analgesia and anesthesia to alleviate this pain has been studied by many researchers. This review article also aimed to assess different methods of analgesia and anesthesia to achieve a comprehensive result regarding the issue. The present study was a review of more than 50 articles on the methods of analgesia during IUD insertion. The articles are available in PubMed, Elsevier, and Google scholar databases. Unfortunately, no acceptable and ideal way has been found for reducing pain during IUD insertion. Although para-cervical block showed satisfactory results, more studies and clinical trials are required to be conducted in this area.
